Exact changes made for Auto Start/Stop delete option.

[miraculon]

My '22 Ranger has the Auto Start/Stop deleted, per the window sticker and absence of the button.

I have seen that the availability of the "delete" option of this "feature" was due to the "chip shortage".

This is very general, I suspect that there is more to this than the "chip shortage" explanation.

Was a module deleted? (wouldn't this be part of the power train controller?)

Starter changed to a more standard type vs. a special "start-stop" one?

Battery downgrade?

I don't have the wiring diagrams or service manuals for the Ranger (maybe I'll get them eventually), there might be some hints there if anyone has these.

Anyone have a definitive answer? All I can find online is the "chip shortage".

Probably something changed in the ECU programming as many users have eliminated A.S.S. using FORScan.

just feel blessed you don't have it

I think that if it were a parts difference we would see that reflected in the parts catalog. Ford would have to call out if there were a different alternator for trucks without this feature. Same with any other component. I can't think of a component that is exclusive to trucks with or without this feature.. (Except for the button.)

There is a heater coolant circulating electric pump and an electric transmission fluid pump for A.S.S. that might be elimimated.

That's the first I hear of that. Why would it need those?

To keep heat in the cabin and the transmission clutches engaged when the engine is stopped.

I do. My 2018 AWD Fusion doesn't have the auto-start-stop either. Lucked out both times...

I have 22 - with ASS delete as well -
There are 3 settings with Forscan that tie into the ASS
1. disable Bms - witch in turn disables ASS
The 22 has this still enabled

2. Ford - removed the switch - physically

3. Ford - disabled the switch and the IPC screen accociated with ASS - electronically
Owners can do the same thing with Forscan - and still keep BMS funct
I have all the settings posted here but have to find them

Now I don’t know if the coolant pump is still installed - never looked at that - but just love the fact I don’t have that ASS - even if I did - it would be deleted anyway
These are the only changes I know of as like you I was curious and dove into how Ford deleted the ASS system

Edit:
Found Them:

Factory Enabled - . BCM - 726-48-02 - 0100-0000-0179, Ford left this setting enabled, and owners use this setting to delete the ASS but also disable the BMS system along with it by changing it to this. x0xx-xxxx-xxxx)

Factory changes to the Switch (Disable)
FCIM - 7A7-01-01 - 0076-80DC-1496, Trucks with the ASS switch will have this xxxx-x1xx-xxxx

Factory changes to the IPC (ASS) Screen (Disable)
IPC - 720-01-01 - 2FOF-1464-7251 , Trucks with ASS will have this 3xxx-xxxx-xxxx

So, this only changes that I know of are the switch (Deleted) Physically and the above programming changes to the modules. So this leads me to think that the chip shortage tied to the switch itself
The Battery is the same and no documented parts differences between the trucks such as starter and related parts, the Cabin Coolant pump if deleted is not needed anyway, as its only function was to electrically circulate coolant through the heater core for cabin heating while the ASS was (Active) and engine was not running.

Plus, my thinking is that owners can accomplish the same thing by changing the FCIM and IPC settings and disable the ASS just like Ford did, the only unknown is - the system may see the switch installed and generate a fault, might have to jumper the switch connector or remove it, I think the aftermarket eliminator basically does this and simulates pushing the switch at each start up, without the programming changes.
So owners with ASS that want to disable, these are the only known changes that Ford themselves made to disable the system, might give them a try to see if they work and zero faults generated.

I did find this at https://www.ford-trucks.com/forums/1654547-auto-start-stop.html

"The PCM sends a PWM signal to control the cabin heater coolant pump. " per the 03-06-2021, 12:23 PM post.

There might be a driver module that has power semiconductors that are capable of driving a pump motor. This is speculation on my part.

More interesting is this web page: https://gearsmagazine.com/magazine/fords-6f35-auto-start-stop-function-and-repair/

See figure 6, there is a module for the transmission pump. This is a pretty comprehensive article regarding start-stop.

I would like to know what if anything was done to the plug that connects to the switch in the center console for deletes. Jumping 2 of the wires sets the ass to permanently off, so wondering if a plug was installed there?

When I had the factory 8” screen in my 2020 Ranger the ASS button would reset itself to being ON after every off/on cycle of the engine after I manually turned it off. After i got a new stereo system with Maestro, I can turn it off or on and it stays with the last setting I put it on. I appreciate that. I was annoyed to have to turn it off every time I started the truck especially in cold weather so the engine isn’t constantly stopping and starting again while its still warming up as I am navigating out of my neighborhood. I feel like thats bad wear on an engine.

My '23 has the ASS Delete, I can confirm there IS an aux coolant pump, and I'm 99.9% sure the pump is still in the transmission. It would have been cost prohibitive to make mechanical changes to eliminate a simple electronic option.

Yes, the only DELETED part is the ASS Switch, confirmed after a deeper look and verification of Cabin Heater pump still installed.

The Cabin Heater Pump is still installed but will not electrically activate unless it receives the trigger to turn it on (1) ASS Active and Engine Off and (2) Climate Control System - In Heat Mode
So, the part is physically installed but not operational.

Verified via As-Built Comparisions between a Truck with ASS and My 22 with the ASS Delete ($50.00 Credit)

2ea - Module Changes
1- Disable The Switch (Input) in the FCIM Module
2. Disable the IPC (ASS Screen) in the IPC Module

FCIM:
7A7-01-01 (0076-81DC-1497) ASS Enabled Truck - Switch Enabled
7A7-01-01 (0076-80DC-1496) ASS Deleted Truck - (Switch Disabled) (Mine)

IPC:
720-01-01 (2F0F-3464-7271) ASS IPC Screen / Indicator - Enabled
720-01-01 (2F0F-1464-7251) ASS IPC Screen/ Indicator - Disabled (Mine)
